PN placement:ALP|Autophagophore initiation and elongation|Class 3 PI3K complex 1, direct|Class 3 PI3K complex 1 component (row 1) and ALP|Autophagosome closure maturation and lysosome fusion|Class 3 PI3K complex 2, direct|Class 3 PI3K complex 2 component (row 2) ; PN-node mapping: both type leaves mapped, ok_for_propagation_to_go → GO:0034271 (C1/type I) and GO:0034272 (C2/type II); group/class/branch ancestors all context_only/no_mapping.
Consistency: Strong. Notes, review YAML, and PN all model PIK3R4/VPS15 as the regulatory/scaffolding subunit of class III PI3K complexes (PI3KC3-C1 and -C2), not the catalytic kinase. Review description and core_functions name both complexes explicitly. No contradictions.
PN story / NEW pressure: Already captured. PN asserts membership in both class III complexes; review ACCEPTs GO:0034271 and GO:0034272 (both already IBA in GOA — PN goa_status already_in_goa_exact). No NEW GO term needed. Verdict: already captured.
Mapping strategy: Correct and unchanged by this gene. The two type-leaf mappings to GO:0034271/GO:0034272 are the right grain; ancestors (GO:0035032 class III PI3K complex; GO:0016236 macroautophagy) are correctly held as too_broad_to_propagate, consistent with the TRAPP-overpropagation precedent. PN-projected terms are neither broader nor narrower than the review — they coincide.
Evidence alignment: Partial overlap. PN cites review-style sources (Annual Review; Yang & Klionsky; PMID:19270696 Matsunaga Atg14L/Rubicon Nat Cell Biol). Review uses primary literature: PMID:8999962, 25490155, 40442316 (PI3KC3-C1 structure), 19270696, 20643123, 14617358. PMID:19270696 is shared. Review also flags VPS15 as a pseudokinase (PMID:40442316) and REMOVEs yeast nucleus-vacuole junction, MODIFYs pexophagy→autophagosome assembly — finer than PN.
Verdict: Consistent; PN complex membership fully captured by existing GOA + review ACCEPT. No new GO pressure; mapping grain correct. No edits required.
